To all whom it may concern:

Be it known that I, LUciAN C. JACKSON, a citizen of the United States, residing at Buffalo, in the county of Erie and the State of New York, have invented or discovered a certain new and useful Improvement in Means for Controlling and Regulating the Operation of Gas-Engines, of which the following is a specification. i

The object of my invention is to provide improved means for controlling and regulating the operation of gas engines; to pro-l vide improved features of rconstruction to render the same simple, eiiicient and certain in action; to prevent unsteadiness in action of throttling valve and governor, and to combine in a novel regulating apparatus for automatic engines the advantages obtained in the hit and miss type, whereby the charge of air and other gases is conveyed separately to a mixing chamber; and at the same time varying the capacity of, or entirely closing, the supply passages through which said air and other gases are supplied to the cylinder or cylinders of a gas engine, and whereby the quantity and relative proportions of the air and other. gases may be varied and the mingling of the' gases eHected in the mixing chamber, all as hereinafter set forth.

In the accompanying drawings, Figure 1, is a central longitudinal section through the axis of my improved apparatus and showing connection to two mixing chambers and puppet valves for controlling passages from said mixing chambers to two combustion chambers in a gas engine; Fig. 2, a front elevation of the casing shown in section in Fig. 1; Fig. 3, a central longitudinal section through the axis of my improved valve apparatus showing openings for admitting air and other gases to the casing; Fig. 4, a transverse section on line A-B of Fig. 1, showing the connection between valve casing and mixing chamber divided in two parts; Fig. 5, a transverse section on line C-D of Figs. 1 and 3; Fig. 6, a transverse section on lines E-F of Figs. 1 and 3; Fig. 7, a central longitudinal section through the axis of a modification of the valve apparatus is effected by the hand operated devices;

Fig. 13 a front elevation, and Fig. 14, a .side elevation, partly in section through openings 63, and 65,;of Fig. 1, of myfimproved valve apparatus, showing a pipe and `valve for controlling any unsteady move ment of the valve.y

In'the drawings of my improved apparatus, the casing 1 is provided with a bushing 2 which incloses the sleeves 3 and 4 which in turn inclose the valve 5. The

casingA 1 is provided at one end with an annular chamber 6 surrounding the bushing `2 and having an air supply port 7. At the opposite end of casing 1 is an annular chamber 8 surrounding the bushing 2 and having a port 9 by which the other gases are admitted. The bushing 2 is provided with large ports 10 opening into the annular chamber 6 which are adapted to register lwith ports 11 in sleeve 3, and which in turn register with ports 37 in valve 5. Ports 10, 11 and 37 are always open to freely admit air from the air supply port 7 to the chamber 12 of valve 5. In the same manner the opposite end of bushing 2 is provided with large ports 13 opening into the annular chamber 8 which are adapted to register with ports 14 in sleeve 4, and which in turn register with ports 38 in valve 5. Ports 13, 14 and 38 are always open to freely admit gas from the supply port 9 to the chamber 15 of valve 5.

Valve 5 is divided into two parts by the forming a perfectly balanced valve device of valve 5.

As shown, my improved valve apparatus contains a valve having tWo separate chambers with their port controlling sleeves, for separately throttling and controlling the air and other gases, but I do not limit myself to any number of chambers or controlling sleeves as one or more may be used.

The chamber 12 of valve 5 is provided With ports 16 which are adapted to register With ports 17 in sleeve 3 and which in turn register With ports 18 in bushing 2. The passages 19 and 20 lead from the annular chamber 21, shown in Figs. 3 and 6, to the mixing chambers 22 and 23. rIhe chamber 15 of valve 5 is provided With ports 24 Which are adapted to register With ports 25 in sleeve 4, and which in turn register With ports 26 in bushing 2. The passages 27 and 28 lead from the annular chamber 29, shown in Fig. 3, to the mixing chambers 22 and 23.

The air admitted into the chamber 12 from the annular chamber 6 and supply port 7 passes through the ports 16, 17 and 18 of the valve 5, sleeve 3 and bushing 2 to the annular chamber 21 shown in Figs. 3 and 6. The gas admitted into the chamber 15 from the annular chamber 8 and supply port 9 passes through the ports 24, 25 and 26 of the valve 5, sleeve 4 and bushing 2 to the annular chamber 29 shown in Fig. 3.

When valve 31 is opened, the air from annular chamber 21 and gas from annular chamber 29 are sucked through passages 19 and 27 to the mixing chamber 22 Where they mingle and are then drawn into a cylinder or combustion chamber of the engine, not shovvn, through the passage 33. In the same Way When valve 32 is opened, the air and gas from annular chambers 21 and 29 are sucked through passages 2O and 28 to the mixing chamber 23, Where they mingle and are then drawn into another cylinder or combustion chamber of the engine through the passage 34.

My invention is shown communicating With tWo cylinders or combustion chambers of an engine but it is not limited to any number as it is adapted to supply one or more.

The bushing 2 is fitted tightly in casing 1 While sleeves 3 and 4 are provided With handles 35 and 36, by Which they may be moved by hand and in either direction to effect any desired opening of the ports 16 and 24, or to entirely close them. The fit of the sleeves 3 and 4 in the Casing 2 is preferably of such a character that they may be easily moved by hand but sufficiently snug to hold them in any position in which they may be placed, though any convenient locking device may be used. Valve 5 is closely iitting but freely moving in the sleeves 3 and 4.

For convenience in manufacturing I have shown the bushing 2 in casing 1 but it is not essential to my invention as the casing 1 can be cast in one piece With 2. The ports in casing 2 registering With ports in sleeves 3 and 4 may be made much larger than shown if desired as the movement of the sleeves 3 and 4 Will still vary the openings of the ports 16, 17, 24 and 25. The handles 35 and 36 are provided With pointers 39 and 40 to indicate on the graduated scales 41 and 42, to what extent the ports 16, 17, 24 and 25 are open.

In Figs. 1 and 3, the outer ends of the sleeves 3 and 4 are shown in contact with ends 43 and 44 of the casing 1, and their inner ends in Contact with each other. Sleeve 3 is then adapted to be rotated by the handle 35 to effect any desired opening of the ports 16, and 17, but should not materially a'ect the size of the openings through the large ports 10, 11 and 37, through Which air is admitted to the chamber 12 of the valve 5. In the same manner sleeve 4 is adapted to be rotated by the handle 36 to effect any desired opening of the ports 24 and 25, but should not materially affect the size of the openings` through the large ports 13, 14 and 38, through Which the other gases are admitted to the chamber 15 of the valve 5. It is obvious that other means may be employed to operate the sleeves 3 and 4 Without departing from the spirit of my invention.

In Fig. 1, holes 64 and 66 are tapped through ends 43 and 44 of casing 1, and communicating into openings 63 and 65 of sleeves 3 and 4. The openings 63 and 65 (see Fig. 14) are elongated and of such a shape as to be always in communication With 64 and 66. These holes 64 and 66 are then connected together by means of pipe, 75, Figs. 13 and 14. This allovvs the air over one end of valve 5 to pass to the other end as the valve is moved up or down and so prevent a vacuum being formed between the ends of valve 5 and sleeve 3 or 4. An ordinary index valve 76 is inserted in the pipe 75 between holes 64 and 66. The amount of opening through this valve 76 in the pipe 75 can be regulated and so act as a dash pot to steady the movement of valve 5 from one position to another. Under the iniiuence of the governor While hunting, caused by improper setting of throttling valve, improper design or construction of throttling valve or governor; or by sudden changes of load, the throttling valve and governor have an unsteady and jumping motion Which this the base 58, and is rotated by the gears 59 arrangement prevents. The valve 5 is so connected to a governing device that it may be moved longitudinally to vary the capacity of the ports 16, 17 24 and 25 but my invention is not limited to any specic governing device or connections thereto.

In Figs. 9 and 10, a centrifugal flyball governor is shown mounted on a shaft 45, and rotating with it, and being connected to the valve 5- by means of a yoke 46, shaft 47, lever 48, links 49 and rod 50. The balls or weights 51, are pivoted to the governor body 52, by the pins 53, and connected to the shaft 45, by kmeans of pins 54 and sliding blocks 55, and held against the action of centrifugal force by the springs 56. The shaft 45 has a flange 57 for supporting it in and 60 and shaft 61, which is operated from the motor. Shaft 45 is held from endwise movement by the flange 57 and gear 59, and in rotating drives the governor body 52, by means of the feather 62, which allows the governor to rise and fall and so impart through its connections a longitudinal movement to the valve 5 for varying the openings through the ports 16, 17, 18, 24, 25 and 26. The quality of the mixture of air and other gases in the mixing chambers 22 and 23, is regulated by adjusting the sleeves 3 and 4 by means of the handles 35 and 36. This is accomplished by giving the sleeves 3 and 4 a partial rotation by hand which adjusts t-he relative sizes of the openings through them and so secures any desired proportion between the air and other gases passing from the chambers 12 and 15 of the valve 5, to the chambers 22 and 23, where they are mixed and then admitted to the cylinders or combustion chambers of the engine. The valve 5 which is connected to and controlled by an automatic governor, has a longitudinal movement for securing any desired quantity of the air and`- other gases admitted to the mixing chambers, and this is accomplished without varying the proportions and hence the quality determined by the position of the sleeves 3 and 4. The valve 5 has only a longitudinal movement and by means of the automatici, governor regulates the amount of air and other -gases required in accordance with the speed of the motor; but the proportions of air and other gases may be varied at any time and independent of the operations of the governor, without disturbing it in any way, by the movement of the sleeves 3 and 4. Y

My improved valve device is not a mixing but a throttling valve apparatus and the air and other gases passing through it are throttled and conducted separately to a mixing chamber where they partially mingle before entering the combustion chamber or cylinder of the engine. This is an important `ready to be red.

:feature of my invention and prevents back firing or premature ignition of the charge while being drawn into the engine cylinder and coming in contact with the flame from the previous charge as frequently happens. The mixing chamber is of such a size as to allow the air and other gases to commence to mingle so they will only be properly mixed when compressed in thel engine cylinder and When the gas and air are thoroughly mixed in a valve or chamber some distance from the engine cylinder and then come in contact with the flame from a previous charge while being drawn into it, the entire mixture is ignited and causes a loud explosion back through the air-pipe into the engine room. Air and gas are not explosive unless mixed in the proper proportions and by keeping them separate and not allowing them to be thoroughly mixed before entering the combustion chamber of an engine, as with my improvement, any llame remaining from a previous charge will be extinguished.

In Figs. 7, 8, 11 and 12 Ivhave shown my improved valve apparatus with the valve 5 adapted to be rotated by means of a governor and longitudinal movements of the valve inclosing sleeves effected by the hand operated devices, as my improvement is not limited to a construction in which the valve is connected to a governor for a longitudinal movement only, and in which the hand operated devices have only a rotary movement.

In Figs. 11 and 12 the flyball governor is shown connected to the valve 5 of Figs. 7 and 8, by means of a yoke 46, shaft 47, lever 48, link 67, arm 68, and rod 50, so as toveifect a rotary movement of valve 5. In Figs. 7 and 8,` the handles 35 and 36 are threaded through the ends'43 and 44 of casing 1, with the coarse pitch threads 69 and 70, so as to eiect a longitudinal movement of sleeves 3 and 4. Pins 71 and 72 are fastened into bushing 2 and permit only longitudinaly movement of sleeves 3 and 4 by means of the slots 73 and 74. With the construction shown in Figs. 7, 8, 11 and 12 it will be seen that the valve 5 is rot-ated by means of the governor to eiect variations in the amount of air and gas admitted to the cylinder or cylinders of an engine, while the hand operated devices longitudinally move the sleeves 3 and 4 to effect the proportions of air and gas.

The important features in my improved device are the preventing of t-oo sudden changes in the movement of the throttling valve, whereby a steady action of the same is obtained; the relative or proportional variation of the port openings by the valve under action of the governor and independent of the hand operated sleeves for varying the proportions of air and gas, whereby for all adjustments of the hand operated devices the same degree of opening or closing of the air and gas ports is eEected; and the separate regulating of the air and gas and carrying same close to combustion chamber before allowing` to commence to mix, whereby the advantages of a hit and miss engine are combined in a throttling engine.
